We then put dimensional lumber (2 x 6's) over the barn wood ceiling, connecting to the two Log Crossbeams. Here we are putting dimensional wood rafters in.
Followed by a sheet of the space age "Reynolds Wrap Solar Cooker Stuff" (next to the Tin above)--designed to reflect 95% of the heat (important in the summer with temperatures upwards of 110 degrees Fahrenheit). It also serves as another proection against our wet winters. The Antique Tin goes over the top of the Reynolds Wrap--screwed into the plywood.
The total area of the addition is another 750 square feet of living space. This is all done as a shed roof, in order to make it as simple as possible. The structure is connected to the cabin by several long bolts connected to three hefty posts. I am pleased with the stability of the structure.
